T0 all 'whom/tt may concern: n

Be it known that I, HUGH ARTHUR Ti'ioM- omelectrical engineer, of 81 lVest Regent:

street, inthe city of Glasgow, Scotland, have y invented l'certain new and useful Improved `niain, say at 250V-direct current or otherwise and giving olf a lower voltage in alternating current, which is then passed into the primary side of a step-up transformer from which the desired higher voltage is obtained through the secondary. This high potential current is then conveyed to a number of condenser tubes hereinafter described.

In apparatus for the production of ozonev a series of'open ended cylindrical glass tubes have been employed, each tube being fitted `with an external and an internal wire gauze or ineshed wirework electrode'and arranged in a stack, all the external electrodes being in contact and all the tubes being parallel, the stack being held together by a wooden framework and the whole being placed in a box or casing having an air inlet and outlet; and a series of open ended cylindrical glass tubes each fitted Vwith an external electrode of sheet-metal having punched out tongues andan internal electrode of wire gauze have been held apart and parallel with one another in a framework arranged in a boX or casing having at one end a number of holes to admit air and at the other end an air outlet; and it has also been proposed to regulate the quantity of ozone produced by an ozonizing apparatus by connecting the terminals of the electrodes to a series of com` tacts over which a curved contact piece is adapted-to move so as to place in circuit the desired number of electrodes.

According to my invention, the electrodes, which are-madev of Hollander wire cloth, are placed, one inside and one outside of a glass cylinder or tube of 'any suitable diameter.

V This Hollander wire cloth has usually x10 I meshes to the inch differing from ordinary wire gauze which is ,usually 'of equal meshes to the inch. The .use of this Hollander wire cloth allows a freer passage of air betweenA the cloth and `itu-be and thereby preventing a rise in temperature which would result in o-xids of nitrogen being formed. The tube being of -cylindrical formation there is n0 liability to sho-rt circuiting between the op-v posite polarities; The above condenser tubes which may be of any number are supported by a board of teak wood or other suitable material, at each end of the tubes -by meansv of holes bored to suit and lined with felt to allow of any expansion of the glass. The teak wood boards supporting condensers have holes bored in spaces between the tubes which allow of a free passage of air through the inside and around outside of tubes. By this arrangement the passage for air is so complete that the electrodes are` continually kept cool and the possibility of oXids of nitrogen forming is reduced to a minimum. The ozone produced by this means described generally above is then passed into an extended chainber having'a cone-shaped inlet and a similar outlet.

The invention is clearly set forth-by reference to the accompanying drawings forming part of this specification, which are de scribed as follows Figure l shows in elevation the apparatus herein described, in side and end views. Fig. 2 is a plan. Fig. 3 is across section taken substantially on the line A-B, Fig. 2. Fig. v

As already explained, the alternating current may be obtained from a district supply companys mains, in 'which case there is no necessity, for a rota-ry converter being employed, but if the district supply be a direct current supply the same is then passed into a rotary converter and transformed to alternating. There is also thepossibility of my making use of a storage battery supply, but all these modes of production are equally common property. This supply of alternating current at a suitable periodicity in cycles is passed into a step-up transformer at the primary terminals and givesof. a charge of `high potential 'at the secondary terminals.

The said 'transformer is marked 17. From one E, of the' two terminals on the primary ioo side of the step-up transformer a connection 24 is carried to ammeter 18, from thence a wireconnection 23 is carried to a plug tei"- ratus by connection 22. From the other terforine'l? and joined 'by means of, a cou ,pling 21, to each and all of the Wires from v"the inner vvHollander wire cloths ofthe con- (vleusertubes in the ozone producing chamv2.'"'From the other F1 of the secondary terminals 'of the transformer 17, a connec- -tion'27fis carried to and connected with the.

lcenterfor' a controller 19. The part of this controller to" which this connection is connected `takes the form of a half circular -`l ';.n`i:fe blade which passes between laminated contcts'thereby cutting the plates intoor 'outfof' action. From the outer Hollander wir'evifelofth surrounding the `glass condenser tub`e,'a connection 28 1s carried to `each of 'thefterminal laminated cont-acts on control- 1er-19. `It `Will `be clearly seen that as the handle 'of controller is turned around, it cuts eutfoi action all or any number of the elecv trodesat will. No claim is 'madetothis cons'truction per se. The ozone'- ithus provduce d,by the process above described, is-

,.-passed .through a cone-shaped inlet ll into an extended oxidizing chamber 3 and thence through a similar outlet 12. y

,The chamber 3 is provided for the purpose of subjecting any suitable substance there in,- such as an oil, drug, or the like, more Ipartieularly'v pils having certain healingproperties 'inl` cases of bronchitis, asthma,

l phthisis, etc., to the` oxidizing miuence of,

the ozone produced in the chamber .2, thereby providing for a suitable medication .of theozone delivered through the outlet 12.

-Thecon'denser tubes 8, 9 and 10 are sup- Vp'ortedgat eachfend by means of a frame of teak .wood or other" suitable material '6.

. vThis' orb'oard has holes 7 cut. to suit the sizes offtubes, which 'vary .according to sizaofapparatus. These holes 7 are shown 3 `andare lined With felt t0 provide easy' resting places androom for expansion, ifanyfof tubes. y T h-e ,electrodes arejcomposed' oi a glass .cylinder or tube 8 prefer-,j

size, and .thenuinbellf 1 will varytaccordto the quantity of'ozone ing to size. of apparatus required. Inside this tube or cylinder 8, a sheet of Hollanderwire cloth 9 soldered so as to make it of 'the saine shape as the glass cylinder or tube 8 and to lit tightly inside is placed with connection" therefrom as previously described. The teak wood, or other boards 6 are provided with holes or spaces 30 between the tubes to admit of a free passage through the inside and around outside of tubes.

On the outer .surface of the glass cylinder or tube 8 a similar piece of Hollander cloth 10 is placed and each' of these outer conductors'are connected as before described to one of each of the terminals of the controller. 4 is the inlet for the, air supply.

and any quantity of air may be drawn or" forced by means of an electricity driven,

or hand or belt driven blower, if desired,

or otherwise.

The extended chamber 3 is. separated by means of a partition L of wood or the like from the ozone producing chamber 2 and lthe Whole apparatus is inclosed in an outer case I, Figs. 3 and 4, and made` ofoak wood, orvother suitable material. i

In operation air passes through the inlet 4 into th-e generating chamber in which the ozone'producer is located, and the oxygenI thereof is converted into ozone which, passing through the cone shaped inlet 11 into the oxidizing chamber. .3, oxidizes the medicaments in -said oxidizing chamber,- th'e resulting .medicated gas being delivered at the cone shaped outlet 12. l
